+ SPECIAL CALL for applications – Paleogene Radiolarian Special-
ist. IODP Expedition 377: Arctic Ocean Paleoceanography (ArcOP)
Dates: Aug–Sept 2022
The proposal upon which this expedition is based was submit-
ted as IODP Proposal #708 ‘Arctic Ocean Paleoceanography’.
Co-chief Scientists: Prof. Rüdiger Stein (MARUM - Center for
Marine Environmental Sciences, University of Bremen, and
Alfred Wegener Institute Helmholtz Centre for Polar and Ma-
IODP rine Research, Bremerhaven, Germany) and Prof. Kristen St.
John (James Madi- son University, Harrisonburg, USA).
Background and Objectives: The overall goal of the drilling
campaign is the recovery of a complete stratigraphic sedi-
mentary record on the southern Lomonosov Ridge to meet
the highest priority paleoceanographic objective: the contin-
uous long-term Cenozoic climate history of the central Arctic
Ocean. Furthermore, sedimentation rates two to four times
higher than those at the site of IODP Expedition 302: ACEX
permit higher-resolution studies of Arctic climate change in
the Pleistocene and Neogene. This goal can be achieved by
careful site selection, appropriate drilling technology, and ap-
plying multi-proxy approaches to paleoceanographic, paleo-
climatic, and age-model reconstructions.
Expertise sought : We are looking for a Paleogene radiolar-
ian specialist (all career stages encouraged) to take part in
Expedition 377 for both the offshore phase and the Onshore
Science Party (OSP).

+ Call for Applications IODP Expedition 398: Hellenic Arc Volcanic
Field
Dates: 6 December 2022 to 6 February 2023
The Hellenic Arc Christiana-Santorini-Kolumbo (CSK) volcanic
field, which includes Santorini caldera and its Late Bronze Age
eruption, provides a unique opportunity to address how sub-
duction-related volcanism impacts life. Better understanding
of island-arc volcanism requires study of the processes that
drive such volcanism, and how the volcanoes interact with
the marine environment. What are the links between crustal
tectonics, volcanic activity, and magma genesis? What are the
dynamics and impacts of submarine explosive volcanism and
caldera-forming eruptions? What are the reactions of marine
ecosystems to volcanic eruptions? The rift basins around the
CSK field, as well as Santorini caldera, contain volcano-sedi-
mentary fills up to several hundreds of meters thick. We pro-
pose to drill six sites, four in the rifts basins and two in Santorini
caldera. Deep drilling is essential to characterize and interpret
the depositional packages visible on seismic images, to chem-
ically correlate primary volcaniclastic layers in the rift fills with
their source volcanoes, to fill in gaps in onland volcanic records, to provide a precise chronostratigraphic
framework for rift tectonic and sedimentary histories, and to characterize the subsurface microbial life.
Objectives:
① Arc volcanism in an active rift environment: To reconstruct the volcanic history of the CSK volcanic
field since the Pliocene by exploiting a >3.8 My marine volcano-sedimentary archive.
② The volcano-tectonic connection: To reconstruct the subsidence and tectonic histories of the rift ba-
sins, and use the rift as a natural experiment for studying the relationship between CSK volcanism and
major crustal tectonic events.
③ Arc magmatism in a region of extending crust: To document magma petrogenesis at the CSK volcanic
field in space and time, and to seek effects of crustal thinning on magma storage, differentiation and
crustal contamination.
④ Unravelling an iconic caldera-forming eruption: To document the processes, products and potential
impacts of the late Bronze-Age eruption of Santorini.
⑤ Volcanic hazards from submarine silicic eruptions: To study the histories, dynamics and hazards of
Kameni and Kolumbo submarine volcanoes.
⑥ Transition from continental to marine environments in the southern Aegean.
⑦ Biological systems reactions to volcanic eruptions and seawater acidification.
Expertise sought We encourage applications from all qualified scientists. ESSAC is committed to a policy of broad par-
ticipation and inclusion, and to providing a safe, productive, and welcoming environment for all program participants. Op-
portunities exist for researchers (including graduate students) in all shipboard specialties, including micropaleontologists,
sedimentologists, volcanologists, petrologists, igneous geochemists, inorganic and organic geochemists, microbiologists,
paleomagnetists, physical properties specialists, and borehole geophysicists. Good working knowledge of the English lan-
guage is required. The Application Process is open to scientists in all ECORD member countries.

+ Call for Applications IODP Expedition 397: Iberian Margin Pale-
oclimate
IODP
Dates: 6 October to 6 December 2022
The Iberian Margin has rapidly accumulating sediment that contains a high-fidelity late Pleistocene
record of millennial climate variability (MCV). Sir Nickolas Shackleton demonstrated that piston cores
from this region can be correlated precisely to polar ice cores from both hemispheres. Moreover, the
narrow continental shelf off Portugal results in the rapid delivery of terrestrial material to the deep-sea
environment, thereby allowing correlation of marine and ice core records to European terrestrial se-
quences. Few places exist in the world where such detailed marine-ice-terrestrial linkages are possible.
The continuity, high sedimentation rates, and fidelity of climate signals preserved in sediments make
this region a prime target for ocean drilling. During IODP Expedition 339, Site U1385 was drilled and
recovered a complete record of hemipelagic sedimentation for the last 1.43 Ma with a mean sedimen-
tation rate of 11 cm/kyr. IODP Expedition 397 will extend this remarkable sediment archive through the
Pliocene and recover a complete depth transect of five sites that will provide a complete suite of down-
hole records with which to study past variability in the major subsurface water masses of the North
Atlantic.
Objectives:
① Document the nature of MCV for older glacial cycles of the Quaternary, including changes in surface
and deep-water circulation during the “100-kyr world”, Mid Pleistocene transition, “41-kyr world”, and
intensification of Northern Hemisphere Glaciation.
② Derive a marine sediment proxy record for the Greenland and Antarctic Ice Cores to examine the
amplitude and pacing of MCV during the Quaternary.
③ Determine interhemispheric phase relationships (leads/lags) by comparing the timing of proxy vari-
ables that monitor surface (Greenland) and deep-water (Antarctic) components of the climate system,
thereby overcoming problems of age determination on millennial and sub-millennial time scales.
④ Study how changes in orbital forcing and glacial boundary conditions affect the character of MVC
and, in turn, how MCV interacts with orbital geometry to produce the observed glacial-to-interglacial
patterns of Quaternary climate change.
⑤ Reconstruct the climate transitions into (inception) and out (termination) of glacial periods at high
temporal resolution.
⑥ Reconstruct the history of changing local dominance of northern-sourced versus southern-sourced
deep water using the depth transect of IODP Expedition 397 sites on orbital and suborbital time scales
during the Quaternary.
⑦ Investigate climate during past interglacial periods, including the warm Pliocene period prior to the
intensification of Northern Hemisphere glaciation.
⑧ Link terrestrial, marine and ice core records by analyzing pollen and terrestrial biomarkers that are
delivered to the deep-sea environment by rivers.
⑨ Contribute to the development of a global stratigraphy having sufficient resolution to study abrupt
climatic events and their phase relationships.
⑩ Interface with projects aiming to recover old ice (including the European “Beyond EPICA – Oldest
Ice” core project) to integrate marine sediment cores recovered during Expedition 397 with existing and
future ice cores from Antarctica.

+ DOVE: Improved drilling progress, Drilling reached 200 m in Basadingen
DOVE (Drilling Overdeepened Alpine Valleys) project is currently under-
way in Switzerland(Basadingen) and Germany (Tannwald). Drilling at the
Basadingen site in Northern Switzerland is on the way to core through a
glacially overdeepened trough filled with multiple sequences of Quater-
nary sediments all the way to the bedrock contact at about 250 m depth.
More than half of the target depth has already been drilled with
excellent core recovery. Drilling at Tannwald includes three boreholes ap-
prox. 160 m deep, two of which - designed for geophysical investigations
with no core recovery -were completed by end of June. The third borehole at the Tannwald site serves to
retrieve continuous core with a scheduled start in early August.
After a break for the installation of an additional casing, the DOVE drilling in Basadingen (NW-Swit-
zerland) is now at 200 m. After slowly coring through a challenging alternation of diamicts, gravels and
sands, the current lithology, which mainly consists of sands, allows for a faster progress.
At Basadingen the DOVE team drills into a 250 m deep glacially over-deepened trough filled with multiple
sequences of Quaternary sediments all the way to the bedrock contact.

+ First Operational Phase of Bushveld Drilling Project underway : Logging 6000 meters
of donated drill cores from the Bushveld complex
The first phase of the Bushveld Complex Drilling Project (BVDP)
was launched in April with drill core logging. At the University of
the Free State in Bloemfontein scientists are currently describing
a 6-km-long drill core that was donated by Impala Platinum Ltd.
The core covers the upper two-thirds of the 9 km-thick Bushveld
layered intrusion. The BVDP project plans drilling approximately
3 km through the lower section of the intrusion and through the
base of the intrusion in late 2021 or early 2022.
Research projects from Germany and South Africa have been funded to commence work on the drill
cores once the logging and documentation is completed. One goal is to identify breaks in the variation
of density and mineral composition with height that may mark episodes of recharge into the magma
chamber. Another is to develop methods to combine EDXRF (energy dispersive X-ray fluorescence),
hyperspectral and LIBS (laser-induced breakdown spectroscopy) scanning to achieve rapid 2-D quantifi-
cation of mineral modes, textures and composition.
Another milestone was now reached in June, 2021, with agreement
by the South African Council for Geoscience to support BVDP with
an in-house Bushveld research unit as well as with resources and
staff at the National Core Library, where the new drill cores will
be housed and about 5000 meters of existing cores, including the
well-known Bellevue core, will be logged and documented for use
in the project.
The second operational phase of BVDP, expected to start in late
2021/early 2022, will involve drilling approximately 3000 meters to
continue the profile through the lower section of the intrusion and
into the floor rocks.

Beneath slow-spreading ridges, melt bodies are generally Hole U1473A (Dick et al., 2019a; MacLeod et al., 2017), in

throughout the lower oceanic crust. We investigated olivine subsequently offset during a period of change in the spread-
gabbros from the plutonic section recovered at the IODP ing direction (Baines et al., 2008).

drilled on the flat top of the dome. In details, Holes 1109A and 735B were drilled during Legs 118 and 176 of the Ocean Drilling Program, and Hole U1473A, stud-
ied here, during Expedition 360 of the Integrated Ocean Discovery Program.Fig. 2: Example of recovered irregular grain-size contacts in U1473A olivine gabbros. (a) Core 74R-7 shows wavy and lobate contact with a close-up (orange box)

IODP Hole U1473A was drilled during International Ocean
Discovery Program (IODP) Expedition 360 into the flat
summit of the OCC (MacLeod et al., 2017). This borehole
penetrated ~810 meters below sea floor (mbsf), recovering
a section of lower oceanic crust mainly composed of olivine
gabbros (76.5 %), less abundant disseminated-oxide gabbro
(containing 1–2% oxide; 9.5% of recovery), oxide gabbro
(>5% oxide; 7.5% of recovery), and gabbro (sensu stricto; 5%
of recovery), and minor felsic veins (1.5%). Throughout the
Hole, primary variations in grain-size (i.e., not overprinted
by crystal-plastic deformation) from fine- to coarse-grained
intervals are copious in olivine gabbros and observed at all
depths (121 contacts; on average one contact every ~4 m of
recovered core). Grain-size variations are mostly irregular
and “patchy”, i.e. sutured displaying variable orientation,
and show coarse-grained domains included into a fine-
grained matrix, with variable thickness of fine- (or medium-)
and coarse-grained intervals (Fig. 2a-b); these grain-size
variations are referred to as ‘irregular contacts’ and were
investigated in Ferrando et al. (2021) and Ferrando et al. Fig. 3: Mg# vs TiO2 (wt%) of clinopyroxene in a representative sample of
(under review). Less commonly, grain-size variations have grain-size contact. We report for comparison variations in clinopyroxene
compositions during: i) melt-mush reaction reproduced in reactive crystalli-
planar and subparallel contacts defining a layering; this type zation experiments of a primitive MORB percolating through a troctolite; ii)

Here, we present the irregular grain-size contacts. sponding to a microgabbro from Hole 735B at 1 kbar.Fig. 4: Schematic reconstruction of the microstructure and chemical evolution from crystal mush to formation of grain-size variations in the studied olivine gabbro. The processes recorded can be summarized as follows. (a) Heterogeneously distributed olivine + plagioclase crystals form after crystallization in-situ (up to 20-30% of melt fractionation) of primitive melts in a crystal mush. (b) Melts within the crystal mush (possibly residual from former minerals crystalliza- tion) begin to migrate through the permeable olivine+plagioclase (±clinopyroxene?) framework and, being in disequilibrium with the more primitive composi- tions of pre-existing minerals, partially dissolve olivine1 and plagioclase1 and concomitantly crystallize olivine2, plagioclase2 and clinopyroxene2; crystals pref- erentially grow and coarse-grained intervals are formed at temperatures of ~1150°C. Note that only plagioclase and olivine display resorbed grain boundaries, while clinopyroxene does not show textural evidences of dissolution. It is possible that few crystals of clinopyroxene1 also formed the pre-existing crystal mush; some crystal cores could represent former clinopyroxene, but we have no certain and clear evidence at this point. (c) The reactive melt migration proceeds at decreasing TL and TS. Melts residual from interaction both crystallize at the rims of pre-existing coarse-grained minerals and are pervasively collected in high porosity zones. In these zones, the delay in nucleation produces an increase in undercooling at decreasing TS that ultimately results in high nucleation rates; new nuclei preferentially form, and the segregated residual melts crystallize to form the fine-grained olivine gabbros at temperatures of ~1050°C.

extracted from the crystal mush and accumulated into dis-

intervals and melt accumulation into fine-grained intervals
was aided by compaction of the crystal mush (Ferrando et

extraction of those melts that in turn potentially contribute
to MORBs erupted at the seafloor.Vidéos
